I have seen a suggestion already about adding fur type to the information when spotting an animal.
This could possibly be implemented as a new, fourth level in the Spotting skill item.
I would also like for the estimated trophy ratings in the spotting information to be color coded based on maximum, estimated trophy rating. That would be much better than having to have a separate spreadsheet up just to see what the trophy ratings mean for an animal before seeing it in the harvest screen.
I think both of these suggestions would be great Quality of Life additions, and would also be totally realistic in my opinion.
